THRAsHlNe-MACHINE.

' SPECIFICATION' forming part of Letters Paterdt No. 469,871, dated 'March 1, 1892.

Application led September 28, 1889. Serial No. 325,365. (No model.) Patented in Norway November 17, 1888, No. 1,222; in England November 21, 1888, No. 16,962, and in Austria-Hungary March 17, 1889, No. 48,364 and No. 9,431.

To all whom t may concern:

Be it known thatI, ERIK GUSTAF NIcoLAUs SALENIUS, a subject of the King of Sweden, residing at Stockholm, Sweden, have in vented certain Improvements in Thrashing Machines, (for which patents have been granted in Great Britain, No. 16,962, dated November 21, 1888; in Austria-Hungary, No. 48,364 and No. 9,431, dated March 17, 1889, and in Norway, No. 1,222, dated November 17, 1888,) of which the following is a specification.

Myinvention relates to machines for thrashing and separating grain, and particularly to that portion of the machine which shakes and carries away the straw when thrashed and the object of my invention isto provide a simple and effective straw-shaker which will effectually shake out all the loose grain.

My invention will be fully described hereinafter, and its novel features carefully defined in the claims.

In the accompanying drawings, illustrative of my invention, Figure l is a side elevation,

mainly iusection, of a thrashing-machine provided with myimprovements. Fig. 2 is a plan of the same, and Fig. 3 is a fragmentary side elevation showing a part of the side opposite to that shown in Fig. 1. Figs. 4 and 5 are respectively a side elevation and a plan, on a large scale, of the preferred form of chain employed in the shaker.

A and A represent, respectively, the major and minor inclined sides of the V-like'grainreceiving chamber B in the machine.

a is the cylinder, and y the feed-hopper. The grain falling to the bottom of chamber Bis carried up over the inclined side A by an endless carrier or conveyer by (Clearly illustrated in Fig. 1.) On reaching the top of side A the grain falls into the compartment B, where the winnowing mechanism is situated.

Mounted on the sides c of the machine is a frame composed of two side plates C, adjacent to the respective sides of the machine, and tie-pieces C', uniting these plates. There are also intermediate longitudinal plates O2 in the frame. Mounted in bearings at the respective ends of the shaker-frame are shafts D D, on which are fixed eccentrically-mounted sprocket-wheels.- I have shown four of these wheels on each shaft; but there may be more or less thanfour. By preference the longer radii of adjacent wheels E on the same shaft will be oppositely arranged, as shown. On the sprocket-wheels E are mounted endless chains F, and each chain is provided with numerous transverse flights or buckets G. In

Fig. 2 only one chain is represented as furnished with flights; but all will be so provided.

Theiiights are omitted from the other chains in order to avoid unnecessary repetition and to avoid obscuring the drawings. In Fig. 1 only a few of the flights are shown for similar reasons. These iiights serve to carry the straw and to prevent falling through the shaker. The shaker and carrier is driven through the medium of the upper shaft D, and this latter mayY beV driven through the medium of pulleys and belts from the motorshaft of the thrashing-machine.

It will be readily understood that while the wheels E operate to propel the chains F, and thus carry the straw upward and outward, the eccentricity of the said wheels will impart a certain lateral vibration to the chains which will thoroughly shake the straw in its upward travel.

In order to impart an additional lateral Vibration to the chains at or near the middle parts thereof, I mount under the upper strand of each chain F a wheel F2, rotatively mounted in forks or arms projecting radially from'a rock-shaft F', which shaft is journaled in the plates C. The shaft F is rocked by means of a crank F3 on the upper shaft D, which is coupled by a link F4 to an arm F5 on the shaft F. This construction is best illustrated in Fig. 3. After leaving the shaker the straw falls on adelivery endless apron H.

Vhile it is not essential that the frame of the shaker be made movable and adjustable or that said frame shall have any special construction, I prefer to, and usually do, mount said frame pivotally on the sides c of the thrashing-machine. This may be effected by providing the side plates O with eXteriorlyprojecting trunnions d and furnishing the latter with bearings on the upper edge of the sides c. This construction enables the inclination of the shaker to be varied without difculty.

In order to prevent the straw from wrap- IOO ping about the shafts D, shields D may be employed. These may be made of sheet metal, secured to the ties C and slitted to embrace the eccentric wheels E. The free end of the shield is curved so as to house the upper side of the shaft. Only a portion of one of these shields is seen in Fig. 2.

The chain of the delivery-apron consists of rectangular links R, arranged to overlap to an extent sufcient to enable the branches of the U-shaped hinge-piece R to be passed up through them, so as to hinge them together. The flight G is secured between the said branches, as clearly shown. If it is not desired to employ a flight at every short link, the ends of the branches of the piece R may be bent or clinched over the links, as seen at R3. This is the kind of chain-I employ by preference for the chains F in my shaker.

Having thus described my invention, I claim-.-

1. In a th lashing-machine, the combination, to form a straw carrier and shaker, of the sprocket wheel shafts, the eccentricallymounted sprocket-wheels fixed thereon, the endless chains mounted on said wheels and provided with flights, and the intermediate vibrator consisting of the rock-shaft, mechanism for rocking the same, and the wheels F2, mounted on arms that radiate from said shaft, said wheels being arranged under the respective chains of the carrier and the eccentric sprocket-wheels being arranged in the order set forth.

2. In a thrashing-machine, the combination, with the frame of the shaker pivotally mounted on the machine-frame, whereby its inclination may be Varied, of the sprocketfwheel shafts mounted in said frame, the sprocketwheels mounted eccentrically on said shafts, and the endless chains with flights mounted on said wheels, substantially as set forth.

3. The endless chains F of a straw-carrier, each consisting of overlapping links R, U- shaped hinge-pieces R', and flights G, the flight being embraced between the branches of the hinge-piece, as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
